First you must know that is i∧2= -1
x∧3-4x∧2+4x-16 = x∧2 (x-4) + 4 (x-4) = (x-4) (x∧2+4) = (x-4) (x∧2-(-4)) =
= (x-4) (x∧2-(-1) *4) = (x-4) (x∧2- i∧2*2∧2) = (x-4) (x∧2-(2i)∧2) = (x-4) (x-2i) (x+2i)
Good luck!!!
Answer:
B.
Step-by-step explanation:
Since we are moving the graph f(x) to the right 2 and down 1 with a reflection over the x-axis, we modify <em>a</em>, <em>h</em>, and <em>k</em> in f(x) = a(bx - h)² + k:
We would get f(x) = -(x - 2)² - 1 as our answer.
Answer: 38/45
Step-by-step explanation:
4/10 + 4/9
Lowest Common Multiple of 9 and 10 is 90. Rewrite fractions as 36/90 and 40/90. Add the numerators to get 76/90. Simplify that and you get 38/45, or 0.8444 (four repeating).
Answer:
35% of 40 = 14; 40 - 14 = 26.
Step-by-step explanation:
The friend added the 35% (14) of 40 instead of subtracting, which is what we'd need to do in this situation since the question says 35% off.
Since they added the 14, it came out of $54.00 which is incorrect. The true value (with discount) = $26.00.
To get the denominator you would have to multiply w+5 by w-4
And whatever you do to the denominator you have to do to the numerator
(w-3)(w-4)
w^2-3w-4w+12
w^2-7w+12
So your answer would be c
